I'd like to know how do you expect the governments or even private institutions to enforce this since most of the countries won't care about foreign laws.

All of these models retain a representation of the original training data in their parameters, which makes training a violation of copyright unless it was explicitly authorized.

How can you argue it's copyright violation while also saying the law hasn't caught up?

The law just hasn't caught up yet

The legal grounds are that the AI is trained using voice lines that can indeed be copyrighted material. Not the voice itself, but the delivered lines.

I think this could technically fall under name, image, likeness rights. Your voice could count as likeness and can't be used without your concent. I know the big movie studios need to get permission from the family to do their creepy dead actor cameos like Disney did with Peter Cushing. I think this would be the same.

Humans can't entirely replicate one another's voices. I recognize voices far better than faces, and I know I'm not the only one out there who does so. There are a lot of good imitators out there, but they can't replicate another voice.

Frito lay copied Tom Waits voice and he sued. He won. I think the judge even got him more than he asked.

It is a can of worms we were going to have to figure out either way. The power of these tools are impressive but they can get a little out of hand as shown with fools making NSFW mods with them but that is only one aspect. We have to keep in mind we can see companies screwing VAs out of jobs because of this tech as well which will likely have far more importance. In a way this tech can also be liberating for bad actors since we are now entering into a new phase of "Post truth" reality or I guess it may be better to say the democratization of fake news/false narratives, we were already at the door of this era but these AIs put us way past that door now. Its rather unfortunate since the power of this stuff can lead to some insanely cool concepts. Like the idea that fans could in theory restore cut content from games and even be able to replicate voice acting to make it feel closer to the original game. Hell how about inserting voice acting in games that never had it or were nonviable to have voice acting for every character in things like Baldur's gate, neverwinter nights, planescape torment, original fallouts, etc. Many of these games are beloved classics but they are sometimes missing some of the things we are used to in more modern games.

I don't think it's a good idea to have it be illegal to sound similar to another person.

Who’s Joan? My Netflix only has a Madison_rogue is awful episode.

But in all seriousness, the tech is here and it’s here to stay. Legal stuff can curb it for a bit, but you know internet. It’s only going to grow.

There should be some other way to deal with it besides “Forbid everything now!”.

I’ve seen several future copyright systems being discussed which might provide a better way of doing things going forward. Like the one where all copyright is basically waived, but royalties are collected and distributed to all participants from any derivative work. Want to make a star wars fan movie? You’re free to do so (and everyone is), but every actor you use and every writer whose part of the lore you’re using gets a small cut from whatever to earn on it (so non-profit derivative work doesn’t require paying royalties, similar to parodies in the US).

Kinda like sampling in music currently works. Could be a better system than what we currently have, with corporations owning hundreds of years of usage for one story or likeness.
